[CQ-Contest] WW Digi Contest

[Oliver Dröse]

Easy ... use a Flex 6600, 6700, 8600 (or the according M models).

They provide 2 SCUs and allow full-duplex operation. So TX one period on one band while listening on a 2nd band and next period vice versa. Been there done that. ;-) The only problem is the transmitter / PA stage is operating at almost 100% duty cycle then (to be exact, 27 out of 30 seconds per FT8 period, so 95% "on-time"). Even just doing QRP last weekend the TRX blowers were running at high speed all the time ...

Not sure how well the future Aurora 520 will handle that at 500 watts. ;-)
